Comprehensive Evaluation of Dam Safety Monitoring System: ( Ⅳ ) Example
At present, the evaluation of working status of the differential resistance strain gauge is still insufficient in terms of comprehensiveness. So, here, taking the working status of the differential resistance strain gauge in Liangqian Hydropower Station as an example, the content, methods, standards and grades of comprehensive evaluation for the differential resistance strain gauge are systematically studied from the aspects of field survey, site testing and long-time observation accuracy by use of qualitative and quantitative analyses. The research results can provide reference and experience for evaluating the working status of the differential resistance strain gauge.
